Making Smart Equipment Decisions

Large equipment purchases can make or break a growing company. Forklifts, manufacturing machines, and specialized vehicles often come with price tags in the tens or hundreds of thousands of dollars. Business owners must decide whether to buy equipment outright—usually with financing—or to lease it. Each option affects cash flow, taxes, and maintenance obligations differently. Our Equipment Lease vs Buy Calculator simplifies the math so you can focus on strategy.

The Financing Formula

Buying with a loan spreads the cost over several years. The monthly payment for a loan of principal $P$, interest rate $r$, and term $n$ months follows the familiar amortization formula:

$$M=\frac{Pr{\left(1,+,r\right)}^n}{{\left(1,+,r\right)}^n-1}$$

Leases usually require lower monthly payments, making them attractive when cash flow is tight. However, you don’t build equity in the equipment. Leasing also tends to cost more overall when the equipment has a long useful life. The calculator compares the cumulative lease payments to the total cost of financing minus any residual value when you sell or trade in the equipment.

Factoring in Taxes and Deductions

In many jurisdictions, lease payments are fully deductible business expenses. Loan payments are not deductible, but depreciation and interest often are. Because tax regulations vary, this calculator focuses on the pre-tax cost comparison. For the most accurate picture, consult your accountant about local depreciation schedules and deductions. Adjusting the residual value field to include tax savings is one workaround for advanced users.

Table: Sample Cost Comparison

Scenario	Total Lease Cost	Total Loan Cost
High Interest, Short Lease	$58,000	$53,000
Low Interest, Long Lease	$45,000	$47,500

The table above shows how lower interest rates can tip the scales in favor of buying, while generous lease terms may offset higher financing costs. Your numbers may differ significantly.

Beyond the Spreadsheet

Cost isn’t everything. Leasing allows you to upgrade to new technology regularly without worrying about resale logistics. Buying gives you control over maintenance schedules and modifications. If your industry changes rapidly, leasing might keep you competitive. But if equipment lasts decades with minimal upgrades, buying could be the better bet. The calculator’s real power lies in modeling these scenarios quickly so you can focus on strategic considerations like downtime, training, and the pace of innovation.

How to Use the Results

After you hit calculate, the tool displays the total cost of each option. A lower number indicates the more economical choice, but you should still weigh flexibility, tax implications, and cash flow needs. Many companies use a hybrid approach—leasing some equipment while buying other assets outright. Rerun the calculator whenever your financing terms or operational requirements change. By staying informed, you can allocate capital efficiently and avoid unpleasant surprises.

The added tax rate field applies a simple percentage to both options so you can approximate after‑tax costs. Once the result appears, click the copy button to save the summary for your records or to share with partners deciding which route works best.

Limitations

The calculator assumes constant interest rates and lease payments. It doesn’t account for maintenance or insurance costs beyond what you enter. Market conditions may change by the end of your loan or lease term, affecting resale prices and the availability of better technology. Nevertheless, the estimates provide a solid baseline for negotiations with lenders and leasing companies.

In short, our Equipment Lease vs Buy Calculator turns a complex decision into a clear numerical comparison. Use it as part of a broader analysis that includes tax planning, risk management, and the strategic value of owning versus leasing. Armed with this knowledge, you can secure the gear you need to grow while keeping costs under control.
